3 Claims.

This invention relates to an improved perpetual calendar adapted for desk use or the like, and capable of being readily actuated to at all times correctly indicate themonth, date and day of 5 the week.

It is an aim of this invention to provide a dcvice which may be constructed in a variety of attractive designs, consisting of. a limited number of parts coacting in a unique manner to indicate the day of the week and month, as Well as the day of the week for anyday of the month at a glance.

' It is a further object of this invention to provide a device as aforementioned, which will be economical in construction, durable and capable of being quickly and easily operated for setting at the end of, each month and each day.

Other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing which illustrates a preferred form of the invention, and wherein:

Figure'l is a front elevational view of the device,

Figure 2 is a vertical central sectional view of the same with the stand shown partly in elevation,

Figure 3 is a fragmentary front elevational view showing the hub of the pilot wheel calibrated with the months of the year and the number of days in each month, and

Figure 4 is a fragmentary top plan view of. the larger disk.

Referring more particularly to the drawing wherein like reference characters designate like or corresponding parts, I designates a stand or support which may be of any construction desired depending upon the construction of the remaining parts of the invention. Stand I is provided with an enlarged base I I adapted to rest on any suitable supporting surface, and has a threaded bolt I2 projecting through its upper part with its threaded end exposed to receive the disk I3, wheel I4, disk I5 and two nuts I5 which retain parts I3 I4 and i5 in position.

Disk I3 is substantially the same diameter as the rim I'l of the wheel I4, and is provided with seven rows of numerals, designated I8 te indicate the different date of each particular day of. the week of a month, for instance, as seen in Figure 1 Sunday would fall on the rst, eighth, fteenth, twenty-second and twenty-ninth of the month. The wheel I4 comprises the hub I 9 and the seven spokes 20 which project outwardly therefrom. through the rim Il and which have the handles 2| at their free endsy tocomplete the design of av pilot wheel. The seven spokes 20 are adapted to divide the seven rows of calibrations I8 on disk I3 so that each row will be visible through one of the openings in the wheel as seen in Figure 1.

Hub I9 is provided with a reduced outer portion 22 as best seen in Figure 3, which is marked with the 12 months of the year and with the number of days in each month beneath each particular month as seen at 23. Disk I5 is provided with a cut-out portion 24 shaped to expose one of the months and its number of days 23 as best seen in Figure 1.

Between the spokes 20, rim I'I is marked with the days of the week as indicated at 25, so that each of the daysZE is .directly above one of the rows of numerals I8. Disk I3, wheel I4 and disk I5 are rotatably mounted on bolt I2 and normally move together when actuated by one of the handles 2|, but may be moved independently of each other as desired and as will hereinafter be explained.

From the foregoing it will be seen, that disk I5 can be turned relatively to wheel I4 to expose any .desired month through cut-out portion 24, after -which wheel I4 may be turned relatively to disk I3 until the rst day of the month or the numeral 1 on disk I3 corresponds or is beneath the day of the week designated 25 on which the rst day of that month happens to fall. Wheel I4 is then turned with disk I3 until the numeral 1 and its day of the week is at the top. Assuming that the month is May and the first day of the month is Sunday, the wheel I4 will be positioned as seen' in Figure 1 and on the following day wheel I4 will be turned by one or more of the handles 2l l one seventh of a turn counterclockwise to bring the word Monday to the top with the numeral 2 on the disk I3, and this will be continued throughout the month. At the beginning of the next month disk I5 will be turned relatively to wheel I4 one twelfth of a complete turn to expose the month of June and the rst day of the month will then be positioned above the numeral 1 and the operation repeated. In this way it will be seen that an eilicient and practical calendar has been provided which may be used perpetually, and from which it may be ascertained at a glance what particular day of the week any date of the current month will fall on. For instance, onany day of the month by merely glancing at the calendar it can be ascertained that the thirtieth of'. May will be on a Monday.

The wheel I4 could obviously be made in the form of a Wagon wheel or any other of many de signs, Without affecting the operation of the device, and various other modifications and changes may be made and are contemplated, and the right is expressly reserved to make such variations and changes as do not .depart from the spirit and scope of the invention as hereinafter dened by the appended claims.

I claim as my invention:

1. In a device of the class described, a calibrated disk, a wheel-shaped member mounted in front of said` disk and having a plurality of. spokes dividing the calibrated portions of the disk into seven parts, the rim; of said wheel being marked with the days of the week and the hub with the months of the year, a member mounted in front of said hub having a cut-out portion to expose one of the months marked thereon, and a shaft on which said parts are rotatably mounted to move as a unit or separately to perpetually indicate the month, date and day of, the week.

2. A perpetual calendar comprising a stand, a threaded bolt projecting through the upper part of said stand, a disk mounted on the bolt, a Wheel-shaped member mounted in front ofsaid disk, and a second disk Amounted in front of the hub of the Wheel-shaped member and having a cut-out portion to expose a portion of said hub, said first mentioned disk and wheel-shaped member being calibrated to indicate the day of the Week, its month and date, said parts being rotatably mounted to turn in unison or individually as required.

3. A perpetual calendar comprising a pedestal, a shaft mounted in the upper end thereof and projecting outwardly therefrom, a disk mounted on said shaft, a Wheel mounted on said shaft in front of said 4disk and having a plurality of spokes dividing said disk into a plurality of corresponding sections, said disk and wheel being of substantially the same diameter, a second disk mounted on said shaft in front of lthe Wheel and of, substantially the same diameter as its hub, said second disk having a cut-out portion exposing a part of said hub, said disks and wheel being rotatably mounted on the shaft relatively to each other whereby the parts may be revolved selectively or as a unit.
